Multivariable Repetitive-predictive Controllers using Frequency Decomposition [PDF]

, 2012
Repetitive control is a methodology for the tracking of a periodic reference signal. This paper develops a new approach to repetitive control systems design using receding horizon control with frequency decomposition of the reference signal.

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]

, 2018
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

Frequency Adaptive Proportional Feedforward Repetitive Control Based on Farrow Structure Filter for LCL Grid-Tied Inverters

IEEE Access
Traditional repetitive control (TRC) can track current reference signal and suppress harmonic signals simultaneously in grid-tied inverter systems. However, the grid frequency generally varies in microgrid when there is a discrepancy between generated ...
